WOW! Both "Global Warming" and "organic food" are VERY touchy subjects, capable of igniting a lot of very HEATED conversation (kinda like politics and religion).
Personally, I think that "organic" food is pure hype and marketing. A lot of people have reportedly gotten very wealthy hawking "organic" food. Case in point, is the grocery chain Whole Foods (whose stock dropped nearly 40 percent last year when their customers deserted them in droves).
Where I live, many of the supermarkets sport an "organic" produce section where the produce is priced two to three times the normal price. When I read the labels on some of these expensive produce items, they indicated that the country of origin was Mexico, Honduras, Ecuador, etc.
Now I love my neighbors in Latin America, but I REALLY question the "controls" and "inspections" that the Latin American governments exert over their "organic" producers (farmers, etc.).
I suppose if spending more money, often a LOT MORE money, on something labeled "organic" makes you feel better . . . then go for it. But for me, I just do not buy into the hype.
